Over the next few pages we show a range of test shots. On this page the full size image at the minimum and maximum ISO settings have been reduced to let you see the full image, and a series of full resolution crops have taken from original images at a range of ISO settings to show the overall image quality. These ISO test images are shot indoors using reflected natural light for maximum consistency.

----

This is the full frame ar 80 ISO

----

At the minimum ISO setting the image quality is superb, with no visible noise.

----

100 ISO also produces superb results.

----

There is some noise visible at 200 ISO, but it is smooth and unobtrusive.

----

Colour saturation has faded a bit at 400 ISO, the the noise is more visible, but there is still plenty of fine detail.

----

At 800 ISO the noise is worse, but the picture is still quite usable. You can make out the lettering on the spare tyre, which is a good sign.

----

Image quality suffers at the maximum 1600 ISO, but it would still be OK for a small print.

----

This is the full frame ar 1600 ISO.
